A sponge is an animal, not a plant. Sponges belong to the phylum Porifera, which are simple, multicellular animals that live primarily in marine environments, though some species inhabit freshwater.
Lack of true tissues and organs: Unlike most animals, sponges don't have complex tissues or organs, but they are still classified as animals because they are multicellular, heterotrophic (they feed on other organisms), and their cells perform specialized functions.
Feeding: Sponges are filter feeders, drawing water through their porous bodies to trap food particles like bacteria and plankton, which they consume.
Reproduction: Sponges can reproduce both sexually (producing eggs and sperm) and asexually (through budding or fragmentation).
Cellular structure: Sponges have specialized cells, such as choanocytes (collar cells) that help in water flow and food capture, distinguishing them from plants.
Although sponges may seem plant-like due to their immobile lifestyle and appearance, they are a very ancient form of animal life.
